“…However, hospital-associated SCCmec types were also found in this study, indicating a cross transmission between the community and hospital facilities. Moreover, the dominant STs (ST5, ST45, ST59 and ST188) in this study were consistent with other community-based populations [26,[35][36], but some other STs were also previously reported in hospital patients (ST338 and ST1) [37][38][39] and animals ( ST398 and ST1) [40][41][42]. The MLST findings also indicated the cross transmission between communities and hospital settings.…”

Background The global prevalence of methicillin-resistant Staphylococcus aureus (MRSA) colonization in human immunodeficiency virus (HIV)-infected patients is increasing, but data about it was limited in mainland China. This study aims to investigate the epidemiology of MRSA nasal colonization among HIV-infected patients in mainland China and also evaluate the impact of methicillin-resistant coagulase-negative Staphylococci (MRCoNS). Methods This cross-sectional study was designed to collect nasal samples and individual information for HIV-infected participants. Risk factors and phenotypic and molecular characteristics among those with MRSA colonization comparing those with and without MRCoNS co-colonization were analyzed.Results We found 119 (11.89%) out of 1001 HIV-infected patients were colonized with MRSA, including 41 (4.10%) with MRCoNS and 78 (7.79%) without MRCoNS. Having a history of respiratory tract infection in the previous 6 months(adjusted OR=1.64, 95% CI: 1.04-2.57) and male gender (aOR=3.92, 95% CI: 1.20-12.85) were risk factors for the overall MRSA and MRSA without MRCoNS colonization, respectively. No risk factor was associated with co-colonization of MRSA and MRCoNS. The proportions of antibiotic resistance and toxin genes as well as the distribution of molecular types for MRSA isolates were equivalent between subjects with and without MRCoNS isolates (P-value ≥0.05). Conclusions HIV-infected patients remain a highly vulnerable population for MRSA colonization, and men and prior history of respiratory tract infection are risk factors. Risk factors and phenotypic and molecular characteristics of MRSA colonization were not affected by co-colonizing with MRCoNS.

“…Resistance in E. coli and Klebsiella spp. is usually acquired via plasmid-mediated extended-spectrum beta-lactamase (ESBL) production [ 39 ]. EOS caused by ESBL-producing multidrug-resistant pathogen are resistant to beta-lactams, including third-generation cephalosporins [ 40 ].…”

“…However, in some developing countries, community-onset MRSA is becoming more invasive and transmissible and it is becoming increasingly difficult to differentiate this from hospital-associated MRSA (Sunagar et al, 2016). In China, nasal colonization with MRSA was detected in 5.6% of pregnant Chinese women (Lin et al, 2017). Community-onset MRSA infection in Chinese neonates has also been increasingly identified (Li et al, 2015).…”
